Objective To observe the effects of Suoquan Wan(SQW) on the endocrine and immune function of the polyuria rats with kidney-yang deficiency. Methods The model rats were induced by gastric infusion of adenine(250 mg/kg) for 4 weeks, then treated respectively with SQW (at low, middle and high dose respectively), Shenqi Wan and desmopressin for another 4 weeks. The bodyweight and organ index were recorded, and serum cortisone concentration were detected. T cell subsets in peripheral blood were determined by flow cytometry. Results The bodyweight of rats in model group was lower than that in the normal control group. And the bodyweight of rats in desmopressin group, middle-and high-dose SQW groups differed from that in the model group (P < 0. 05 or P < 0. 01). The decreased organ indexes of pituitary, adrenal and thymic glands were found in the model group (P < 0. 05 or P < 0. 01 compared with the normal group). The thymus index was elevated in all the medication groups except the low-dose SQW group (P < 0. 05). The elevated organ indexes of pituitary and adrenal glands were only found in Shenqi Wan group and high-dose SQW group (P < 0. 05). In the model group serum cortisone concentration was decreased (P < 0. 01). In Shengqi Wan group and middle-and high-dose SQW groups, the cortisone concentration was significantly increased (P < 0. 05 or P < 0. 01, compared with the model group). In the model group, the percentages of CD3+ and CD3+/CD4+ T cell subsets in pe-ripheral blood were decreased, and the percentage of CD3+/CD8+ T cell subset was increased (P < 0. 05 or P < 0. 01 compared with the normal group). Compared to the model group, the percentages of CD3+ and CD3+/CD4+ T cell sub-sets were increased and the percentage of CD3+/CD8+ T cell subset was decreased in SQW group and Shenqi Wan group. But the differences of T lymphocyte subsets were insignificant between desmopressin group and the model group. Conclu-sion SQW can regulate the endocrine and immune function of the polyuria ratwith kidney-yang deficiency.

Objective To explore the levels and clinical significance of anti-beta 2-glycoprotein 1 antibodies (β_2GP1), matrix metalloproteinase 9 (M M P-9) in the plasma of children with Kawasaki diseases (KD). Methods Serum level of anti-β_2GP1 antibody and MMP-9 was measured in 47 children with KD by ELISA, and the data was analyzed using SPSS11.5 software. Thirty age matched children with infectious diseases(sepsis or pneumonia), exclusive of heart, liver, kidney, blood diseases and autoimmune diseases such as rheumatoid were chosen in the fever control group. Results Coronary artery lesions (CAL)were found in 17 children of KD group (17/47) by Doppler ultrasound examination. Significant differences (P < 0.05) of serum level of anti-β_2GP1 antibody was showed between KD group ((7.46 ± 2.13) U/ml)and the control group ((4.38 ± 0.43) U/ml) ; serum level of MMP-9 was (886.62 ± 92.72) ng/ml and (460.06 ± 179.59) ng/ml in KD group and the control group respectively, with significant difference between the two groups(P < 0.05). In KD group, levels of anti-β_2GP1 were (8.83 ± 0.89) U/ml among children with CAL and (6.18 ± 1.42) U/ml among children without CAL, serum level of MMP-9 was (948.62 ± 81.76) ng/ml and (872.00 ± 34.74) ug/ml respectively, with significant differences(beth P < 0.05). In children with KD, the serum levels of anti-β2GP1 antibody and MMP-9 were significantly correlated (correlation coefficient r = 0.665). Conclusions Serum levels of anti-β_2GP1 antibodies and MMP-9 increased in the acute phase of KD, and were significantly higher in those KD children with CAL.Anti-β_2GP1 antibodies and MMP-9 may play a role in the pathogenesis of KD, and can be used as an important serological indicator of KD with CAL.

Objective To investigate the expression of Pin1 and cyclin D1 in human pancreatic carcinoma and to discuss its role in oncogenesis of pancreatic cancer.Methods The mRNA expression of Pin1 and cyclinD1 in pancreatic tumor tissues and corresponding adjacent nontumor tissues 27 patients was detected by the real-time quantitative reverse transcription-polymerase chain reaction(RQ-RT-PCR).The results of RQ-RT-PCR were analyzed by one-way ANOVA and Fisher's exact probabilities test.Results Cyclin D1 and Pin1 were overexpressed at mRNA level in pancreatic carcinoma tissues compared with their adjacent nontumor tissues.Cyclin D1 overexpression were found in 14 of 20 pancreatic carcinoma tissue specimens and Pin1 overexpression in 13 of 20 carcinoma tissue specimens.The expression of cyclin D1 and Pin1 in pancreatic cystadenoma tissues was not different than that of corresponding adjacent nontumor pancreatic tissue.Pin1 overexpression positively correlated with an increase in cyclin D1 levels as shown by Fisher's exact probabilities test.However,Pin1 and cyclin D1 expression was not correlated with clinical stage and pathological parameters.Conclusions The overexpression of Pin1 in pancreatic carcinoma tissues could promote cyclin D1 expression,which might be a critical event in oncogenesis of pancreatic carcinoma.Pin1 may play a key role in pancreatic carcinoma.

Aim To study the effects of resveratrol(Res)on the release of soluble adhesion molecules from human umbilical vein endothelial cells(HUVECs)induced by N-formyl-methionyl-leucyl-phenylal-anine(fMLP)and the adhesion between neutrophils and HUVECs.Methods The effects of Res on neutrophils adhesion to human umbilical endothelial cell(HUVECs)triggered by fMLP were examined.The soluble intercellular cell adhesive molecule-1(ICAM-1),the soluble vascular cell adhesive molecule-1(VCAM-1)and E-selectin release from fMLP(10 ?mol?L-1)stimulated HUVECs were determined by ELISA kits.The neutrophils isolated from human vein blood were loaded with Fluo-3,a fluorescent indicator,to detect intracellular free calcium concentration([Ca2+]i),and CLA was used as a chemiluminescent indicator to determine superoxide production in neutrophils.Results Res(1~50 ?mol?L-1)significantly inhibited neutrophil adhesion to fMLP-stimulated HUVECs and also obviously downregulated the levels of ICAM-1,VCAM-1 and E-selectin in supernatant of HUVECs culture stimulated by fMLP in the dose-dependent pattern.Res also suppressed fMLP-activated superoxide generation and[Ca2+]i increase in neutrophils.Conclusions Res involved in neutrophil adhesion to HUVECs intermediated by cell adhesive molecules expression trigged by[Ca2+]i and superoxide production in neutrophils,which means a lot to prevent inflammatory diseases.

Objective To investigate the anti-inflammatory/immune modulatory effects of high-expressing membrane bound M-CSF-hematopoietic malignant cells on macrophages. Methods After coculturing RAW264.7 and murine macrophage cell line with Namalwa-M, a cell line stably expressing mM-CSF, and companing with Nainalwa-V, a cell line stably transfected with the empty vector as the control, flow cytometry was used to detect the expression of the marker of alternatively activated macrophages, CD206, and intracellular expression of IL-10, IL-12, IL-6 and TNF-α to study the immunophenotype of RAW264.7; phagocytic assays to investigate their functional activity in vitro. Results RAW264.7 cocultured with Namalwa-M consistently showed high-level expression of CD206, which indicated activities of these macrophage cells were increased. Furthermore, these RAW264.7 expressing high levels of IL-10, TNF-a and low levels of IL-12, IL-6, as determined by intracellular staining were suggested that the phagocytic activity was increased. Functionally, RAW264.7 cocultured with Namalwa-M showed a higher level of phagocytic activity. Conclusion Macrophage generated in vitro after cocultured with mM-CSF-expressing hematopoietic malignant cell line could be transformed into abnormal macrophage with an immunophenotype defined as IL-10-high, IL-12-low, IL-6-low and TNF-α-high.

This paper was aimed to study the effectiveness and safety of TanshinoneⅡA Sulfonate Sodium Injection in the treatment of unstable angina pectoris (UAP). Keywords such as coronary atherosclerotic heart disease, coronary heart disease, unstable angina, chest impediment, cardialgia, TanshinoneⅡA Sulfonate Sodium Injection, tanshinone injection, tanshinoneⅡA sulfonate, unstable, angina, randomized controlled trial (RCT), and clinical trials were searched in CNKI, VIP, Wanfang and Pubmed from the construction of database until October 31st, 2014. The inclusion criteria were RCT with clinical data integrity, similar literature research methods, and good balance between groups. The Jadad score method was used to carry out quality assessment. Meta-analysis was conducted by RevMan5.2 software. Count data was processed by odds ratio (OR). Measurement data was processed with the weighted mean differences (WMD). The 95% confidence interval (CI) was also calculated. The heterogeneity test result of included literatures was P > 0.05. The fixed effects model was used in the meta-analysis. On the other hand, random effect model was used. For the analysis results of more than 10 papers, the funnel plot was used in the analysis of publication bias. The results showed that a total of 34 studies were included. The results of meta-analysis suggested that the total efficiency of conventional treatment plus TanshinoneⅡA Sulfonate Sodium Injection for UAP was [OR = 3.83, 95%CI (3.11, 4.71),P < 0.000 01]. The electrocardiogram improvement rate was [OR = 3.34, 95%CI (2.61,4.28),P < 0.000 01]; plasma viscosity improvement was [WMD = -0.20, 95%CI (-0.38, -0.03),P = 0.03]; high shear viscosity of whole blood improvement was [WMD = -0.67, 95%CI (-0.85, -0.50),P < 0.000 01]; C-reactive protein improvement was [WMD = -2.66, 95%CI (-3.31, -2.00),P < 0.000 01]. It was concluded that the conventional treatment plus TanshinoneⅡA Sulfonate Sodium Injection for UAP had certain clinical effect with no obvious adverse reaction. However, due to the poor quality of the existing research literatures, the results should be further verified by large amount of high quality RCTs.
